What Are Sintered Bearings
Jan 07, 2026| Sintered bearings are bearings manufactured through powder metallurgy technology, featuring numerous tiny pores inside that can store lubricating oil, enabling self-lubricating functionality.
⚙️ Core Characteristics of Sintered Bearings
• Manufacturing process: Metal powders (such as copper, iron, tin, etc.) are mixed and pressed into shape, and then sintered at high temperature (usually 800-1100 ℃) to combine the powder particles and form a porous structure.
• Advantages of self-lubricating: The pores can store lubricating oil, and during operation, friction generates heat to allow oil to seep out for lubrication, reducing maintenance needs. It is suitable for scenarios where frequent refueling is not easy, such as household appliances and automotive parts.
• Material characteristics: lower density than traditional bearings, lower cost, suitable for mass production, but slightly inferior load-bearing capacity and wear resistance compared to precision machined bearings.
📍 Typical application scenarios
• In the field of household appliances: motor bearings for washing machines and air conditioners, roller bearings for vacuum cleaners.
• Automotive industry: wiper motor, seat adjustment mechanism.
• Office equipment: printer paper feed roller, copier gear shaft.
